Front

What is a leading strand?

Back

Continuous replication towards the replication fork.

Front

What is the role of DNA polymerase in replication?

Back

Synthesizes new DNA strands by adding nucleotides.

Front

What are the nitrogenous bases in DNA?

Back

Adenine, Thymine, Cytosine, Guanine.

Front

What is the difference between the leading and lagging strands?

Back

Leading strand is synthesized continuously; lagging strand is synthesized in fragments.

Front
